EnergyGuard™ PolyIso Insulation

Description
EnergyGuard™ Roof Insulation Board is made of organic/glass facers bonded to a core of isocyanurate foam.

Advantages
• High insulation value—Excellent “R” value compared to any other FMRC Class I rated products of equivalent thickness.
• FMRC Approved—Subject to the conditions of approval as a roof insulation when installed as shown in the current edition of the Factory Mutual Research Approval Guide.
• Environmentally safe—Uses replacement blowing agent that reduces ozone depletion.
• Lightweight—Lighter than most other insulating products offering comparable thermal resistance; as much as five times lighter in weight than many other materials with the same R-value.
• Excellent dimensional stability.
• Low water permeability—lower overall perm rating than many conventional insulation boards.
• High moisture resistance and no capillarity; is stable and maintains its physical and insulating characteristics.
• Easier handling and faster to install—Because of light weight, this material is easier to handle on the job site and installs faster. Easier cutting in the field provides the installer with simplified fabricating on the roof deck. Minimizes on-the-job damage.

Uses
• EnergyGuard™ Roof Insulation is designed for use over structural roof decks where “R” values of 6.0 or higher are required, along with maximum value and comprehensive U.L. and FMRC approvals.
• When properly installed, it is suitable for use under built-up, modified bitumen and most single-ply roofing systems.
• Refer to the application specifications in the current Membrane Manufacturer’s Application and Specifications Manual for proper installation procedures.

Limitations and Potential Fire Hazard
• EnergyGuard™ Roof Insulation is a non-structural, non-load bearing material. It is not designed for direct traffic usage unless adequately protected.
• EnergyGuard™ Roof Insulation should be stored dry and protected from the elements. No more insulation should be installed than can be completely covered with roofing on the same day.
• As unprotected polyisocyanurate will burn, fire safety precautions should be observed wherever insulation products are used.
• Direct torching of modified bitumen roofing to EnergyGuard™ Roof insulation may present a fire hazard. A properly installed fiber glass base sheet MUST be used over the insulation.

Code Compliance
• Listed by Underwriters Laboratories for use under Class A, B or C Roof Covering. See U.L. Inc. Roofing Materials and Systems Directory for details.
• Subject to the conditions of approval as a roof insulation when installed as shown in the current edition of the Factory Mutual Research Approval Guide.
• Mechanical attachment of roof insulation is the most dependable method of attachment to steel decks since it minimizes lateral movement and wind blow-off.
• For details, consult Factory Mutual Loss Prevention Sheet 1-28, 1-29, 1-28R, 1-29R and current Approval Guide.
• Federal Specification HH-I-1972/ASTM C1289 and CCMC 12786-R.

Thermal Values
When calculating the anticipated thermal performance over the expected life of these products, BMCA suggests the use of an R-value of 5.56 per inch of foam thickness (0.98 m2 • °C/W).
